While I am a huge fan of the Versa-Max, the Benelli Vinci is another pretty good "cover all the bases" 12 gauge with very low recoil, which it seems is important to you. I just prefer to buy American guns. I'd be doing some comparison shopping and decide on the one you like the most.
I certainly would not sell an Ithaca 37, but some of the others you have, if you have no reason to enjoy them, shoot them or like them, consider selling them if you really think you have too many. I can pretty much tell you that once you shoot your own Vinci or VM, you will have seen your ideal of a one gun for all filled about as close as you can get. If you sold 3 or 4 of the ones below, you would be well on your way to paying for a VM or Vinci.
